This was described from a single example, which Pease 

 afterward considered to be "a mere variety of C. variabilis. ' ' 

 Pease's account is given in full. No other definite informa- 

 tion bearing upon the forms has been published, but Borcher- 

 ding has figured a shell which he takes to be variabilis. One 

 of his figures is copied, pi. 19, fig. 2. 



40. Var. VARIABILIS Pease. 



Shell elongate-turrite, solid, transversely irregularly 

 roughly raised-striate ; blackish, the suture bordered with 

 yellowish, spire reddish-brown. Whorls 7, flattened; the last 

 two-fifths the length of the shell, sometimes angular below 

 the middle. Aperture vertical, ellipsoidal, blue within ; colu- 

 mella arcuate, somewhat calloused, plicate at the base, white, 

 truncated basally; peristome unexpanded, acute. Length 

 55, diam. 20 mm. (Pse.) 



Var. viridis. Shell wholly green, with no band. (Pse.) 



Kauai: this species is found in a space of over 15 miles 

 on the eastern part of Kauai, therefore occupying a larger 

 area than any other of the genus (Pse.) . 



"The form most nearly related is C. fuliginea Pfr. C. 

 olivacea Pease, which I described from a single individual, 

 is probably only a mere variety of C. variabilis. 



"When the animal becomes adult it vacates the upper 

 whorls; hence the spire in all the living individuals I col- 

 lected is as though dead, decolored and turning light brown. 

 It is probably the largest species of Carelia. I found the 

 last three whorls of a shell which must have had a length of 

 3 inches when living." (Pse.) 



Pease subsequently (1871) mentions, but does not define, 

 a "var. viridans", doubtless an error for viridis.
